i remember during my REME trade training a machine called an izod impact tester. it was basically a weighted pendulum with a ball bearing on the end that hit the test piece with a known amount of force this enabled the material to be rated for hardness by measuring the depth of the indentation. i'm sure carrier armour would have been tested with a machine like that but i'm also sure that most dents you see on a carrier are caused by bullet strikes. my carrier has plenty of dents of varying sizes and 3x 11.5mm holes in the left side panel caused by what i assume to be armour piercing rounds from a boys rifle. if the dents were caused by a measuring machine then the dents would be uniform and all the same depth but if a dent is ragged or oblong it make sense that it was caused by a bullet.
the first pic shows 2 bullet holes on the left panel and the second pic shows the strike marks on the opposite side, the third pic shows a quite large dent but with a flat bottom ? and the last pic shows another penetration hole near the top of the armour that has bent the side with the force of it.
